Debugging 为什么汇编语言会出现语法错误？

我复制了一个汇编代码，试图编译它。然而，它说我在第25行遇到语法错误

Section .text

global _start
_start:

jmp short GotoCall

shellcode:

        pop esi
        xor eax, eax
        mov byte [esi + 7], al  
        lea ebx, [esi]
        mov long [esi + 8], ebx
        mov long [esi + 12], eax
        mov byte al, 0x0b
        mov ebx, esi
        lea ecx, [esi + 8]
        lea edx, [esi + 12]
        int 0x80

GotoCall:

        Call    shellcode
        db      ‘/bin/shJAAAAKKKK’

为什么会这样

Section .text

global _start
_start:

jmp short GotoCall

shellcode:

        pop esi
        xor eax, eax
        mov byte [esi + 7], al  
        lea ebx, [esi]
        mov long [esi + 8], ebx
        mov long [esi + 12], eax
        mov byte al, 0x0b
        mov ebx, esi
        lea ecx, [esi + 8]
        lea edx, [esi + 12]
        int 0x80

GotoCall:

        Call    shellcode
        db      ‘/bin/shJAAAAKKKK’

GNU nano 2.2.6文件：shell.asm

Section .text

global _start
_start:

jmp short GotoCall

shellcode:

        pop esi
        xor eax, eax
        mov byte [esi + 7], al  
        lea ebx, [esi]
        mov long [esi + 8], ebx
        mov long [esi + 12], eax
        mov byte al, 0x0b
        mov ebx, esi
        lea ecx, [esi + 8]
        lea edx, [esi + 12]
        int 0x80

GotoCall:

        Call    shellcode
        db      ‘/bin/shJAAAAKKKK’

你从网上复制/粘贴了它（只是猜测），但它使用了错误的引号：

Section .text

global _start
_start:

jmp short GotoCall

shellcode:

        pop esi
        xor eax, eax
        mov byte [esi + 7], al  
        lea ebx, [esi]
        mov long [esi + 8], ebx
        mov long [esi + 12], eax
        mov byte al, 0x0b
        mov ebx, esi
        lea ecx, [esi + 8]
        lea edx, [esi + 12]
        int 0x80

GotoCall:

        Call    shellcode
        db      ‘/bin/shJAAAAKKKK’

Character: ‘ U+2018
Name: LEFT SINGLE QUOTATION MARK

使用ASCII子集中的单引号：

Section .text

global _start
_start:

jmp short GotoCall

shellcode:

        pop esi
        xor eax, eax
        mov byte [esi + 7], al  
        lea ebx, [esi]
        mov long [esi + 8], ebx
        mov long [esi + 12], eax
        mov byte al, 0x0b
        mov ebx, esi
        lea ecx, [esi + 8]
        lea edx, [esi + 12]
        int 0x80

GotoCall:

        Call    shellcode
        db      ‘/bin/shJAAAAKKKK’

    db      '/bin/shJAAAAKKKK'
